Ford Small Block Aluminum Cylinder Head

• 185cc intake runners support street and mild performance SBF builds

• 60cc heart chambers promote efficient combustion

• Bare casting allows custom valvetrain selection

• Aluminum construction reduces weight and improves cooling

Build your Small Block Ford engine with a bare aluminum cylinder head engineered for street performance, restoration, and custom engine applications. Featuring 185cc intake runners, 60cc heart-shaped combustion chambers, rectangular intake ports, and rectangular exhaust ports, this cylinder head is designed to improve airflow and performance potential across a wide range of Small Block Ford combinations.

The 185cc intake runner design provides an excellent balance of airflow and intake velocity, making this cylinder head well suited for 289, 302, 306, 331 stroker, 347 stroker, and 351W Small Block Ford engines. The heart-shaped combustion chamber design helps promote efficient combustion while supporting improved throttle response, torque production, and horsepower potential.

As a bare casting, this cylinder head allows builders to select valves, springs, retainers, seals, and valvetrain components that match their specific camshaft profile and performance goals. This flexibility makes it ideal for custom engine builds, machine shop assembly, street performance vehicles, muscle cars, hot rods, and street/strip applications.

Constructed from lightweight aluminum, this cylinder head helps reduce weight while dissipating heat more efficiently than traditional cast iron heads. Whether you're upgrading a classic Mustang, building a 347 stroker, or assembling a custom Ford performance engine, this bare aluminum cylinder head provides a strong foundation for reliable power and improved airflow.
